Solar collectors for heating and DHW

Heating and DHW

— devices designed for use both for domestic hot water supply and heating. For DHW, see the relevant paragraph for more details; however, not everything described there is true for this category. For the collector to be effectively integrated into the heating system, it must meet certain additional requirements. First of all, such an application is allowed only for closed devices (see "Loop system") — the heating circuit operates under fairly high pressure and forced circulation, an open loop system is not applicable here. Secondly, the “heating” collector must allow year-round use (see “Additionally”) — after all, the heating issue is most acute in the cold season, and not all models can work at low external temperatures.
